veyers and Elevators, of which the following is a specification.

The principal object of this invention is to provide a baled hayconveyer andelevator which will be susceptible of use in connection withthe ordinary hay-press, and i which may be readily attachable thereto,or detachable therefrom.

My eonveyer and elevator is run by the power of the hay-press, requiringno separate or independent power or, agency for its operation.

A further object is to provide a device of this character which will besimple of construction, and thoroughly efiieient and durable in'use andoperation.

With these objects in View, the invention resides in the novelconstruction, combination, and arrangement of parts, as will behereinafter fully described in the specification, summed up in theclaim, and illustrated in the drawing, in which:

Figure 1 is a top plan view of a hay-ele-' vator embodying myimprovements; Fig. 2 is a longitudinal vertical section, on the line2-2, Fig. 1; Fig. 3 is a detached perspective detail view of one of thespringpressed dogs; and- Fig. 4 is a fragmentary detail view of one ofthe side bars of the frame of the elevator. Figs. 5 and 6 arefragmentary detail views of the runway.

Referring, now, in detail to the drawing: My device preferably includesa wheeled carrier-frame 16, which is, essentially, a platform of anysuitable dimensions. When being transported over the ground, from placeto place, this carrier-frame may be coupled, at its front end, to therear end of the hay-press (not show in any suitable manner. Saidcarrierame is desirably provided, at its rear end, with hooks 13, whichare engaged with the hay-press when the conveyor and elevator is inoperation in connection with the hay-press. end of the carrier-framecarries two upright posts 7, 7, each provided with a vertical series ofsteps 7, any one of which may be engaged by a roller 8, for supportingthe elevator proper (as hereinafter more particularly described).

The front The elevator proper consists of a runway carried by thecarrier frame 16, and formed as an elongated platform, comprising,preferably, a plurality of spaced, longitudinallyextending timbers 17,17, 17, 17, connected by a plurality of transverse bracing-bars 18, 18,

18. Two longitudinally-extending side-bars '9, 9 are disposedvertically, and are suitably secured to the two end timbers 17 ,.andserve ;to hold the hay-bales'on the elevator, against lsidewisedisplacement.

The elevator-runway carries, on its hottom, ways or guides 18, in whichthe roller 8 is slidable, in a direction longitudinally'of the runway.Reciprocable in a direction ,longitudinally of the runway is 'a plun er6, jmovable between two of the timbers 17, 17, 1 nd operable by thehay-press, through suitable intermediate connections, which may takevarious forms, but, in this instance, ,COIliPl'iSG the followinginstrumentalities: ,Suitably secured transversely of the plunger 36 is abar 10 movable in longitudinally-extending slots 4: in the sidebars 9,9of the runway-frame. Pivotally connected with one end of said bar 10 isone end ofa pitnian 2, the other end whereof is pivotally connected withthe .plunger 1 of the hay-press. The bar 10 is preferably braced, at itspoint of connection with the plunger 6, by suitable means, such as asemi-circular, metallic ring 11.

Carried by the plunger 6, on the upper side thereof, is alongitudinally-disposed se ries of metallic dogs 3. These dogs are,

preferably, of peculiar construction and se-.

end, a foot.3 pivotally mounted in vertical side ears 3* carried by aplate 3 detachably secured to the plunger 6, as by screws or the like,passing through apertures 3, provided therefor, in said plate. Bearingupon the rear face of the foot 3 is one end of a leaf-spring 3 secured,at its other end, to the plunger 6, the spring operating to maintain thedog normally in elevated position.

In operation, while the plunger 6 is on its outward or forward pushorstroke, the dogs 3 engage the hay-bales, the spring 3 maintaining thedogs in elevated position; but, when the plunger 6 begins its backwardstroke, the dogs 3 automatically release themselves from the hay-bales,against the A series of these dogs are longitudinally dis- )osed, onpivots, between each pair of timers 17, 17, on either side of theplunger 6. These dogs are not provided with springs, but are weighted,at their lower ends, so as to lie, normally, with their upper, ointedextremities pro ecting above the p ane of the timber 1,7. These dogs areheld, as against movement from the normal, in one direction, by anysuitable means such as stop-pins 5' but, as the hay-balesimove upward onthe run-way, they swing, on their pivots, in'the other direction, so asto occupy a'horizontal position. As soon, how ever, as the plunger 6begins its backward stroke, when the hay-bales have a tendency, ofcourse, to slide backward, said dogs 5 resume their normal, verticalposition and, digging into the hay-bales, check and stop any backwardsliding movement thereof.

By my invention, hay-bales may be elevated to a height of at leastsixteen feet, the elevator and conveyer throwing the bales either onto awagon, or onto a' stack, by means of the power of the hay-press alone,thereby saving the labor and expense of an elevator operated by a powerindependent would otherwise be required in conveying the "hay from thepress and lifting it onto the wagons or stacks, or the like. As will,\of-course, be understood,the plunger 6, by

a series of, strokes, causes the bales to be elee vated in the runway.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

The combination, in a baled hay elevator, of a runway, a plungerassociated with said runway and reciprocable longitudinally thereof,apertured plates disposed on the upper surface of said runway, fasteningmeans passing through said apertures and remova l-y securing said platesto said plunger, dogs pivoted to said plates, springs carried by saidplunger and operatively associated with said dogs and maintaining themin position to engage the hay-bales as the plunger reciprocates forward,and returning said dogs to normal position after depression thereof, andmeans for automatically engaging the hay-bales after release thereof bysaid dogs, on the return 'strokebf the plunger.
